Seaside Path is a 1.4-mile, one-way woodland walk from the Jordan Pond House area toward Seal Harbor. It is a low-grade connector rather than a summit or shoreline hike: most of the route stays under trees, with a carriage-road bridge and a nearby memorial boulder giving it character. Allow about 45–60 minutes one way. Walking back along the same line makes about 2.9 miles total.
The park’s trail catalog lists 1.4 miles; an older description used about 2 miles to Seaside Lane. The current mapped NPS-designated line measures 1.44 miles and ends at a junction near Seal Harbor. A short same-named continuation appears beyond it, but its present public connection to the lane is unconfirmed. Treat this as a one-way mapped route and turn back unless you have verified onward access.
